Our Rating: 5 out of 5
Overall Impression: We really love the Whole Rainbow Blocks collection. The Shimmering Watter variation is one of our favorites along with the Deluxe Set. These are all well made, and tightly fit together. They add a huge amount of play value to the kids unit block buildings. Also check out the Deluxe Rainbow Block Set, the Sand Rainbow Blocks, and the Crystal Bead Rainbow Blocks.
